Thermal Specifications
The cooling solution of a COM Express module is based on a heat-spreader concept.
A heat-spreader is a metal plate (typically aluminium) mounted on the top of the module. The
connection between this plate and the module components is typically done by thermal interface
materials like phase change foils, gap pads and copper or aluminium blocks. A very good
thermal conductivity is required in order to conduct the heat from the CPU and the chipset to the
heat-spreader plate.
The heat-spreader of the MSC module is thermally attached using phase change materials and
small aluminium blocks filling the gap between CPU and chipset dies and the heat-spreader
plate.
The heat-spreader is not a heat-sink!
It is a defined thermal interface for the system designer
with fixed mechanical dimensions, so it should be possible to interchange different module
types without problems. There must be a cooling solution for the system. The surface
temperature of the heat-spreader should not exceed 80°C.
Main issue for the thermal functionality of a system is that each device of the module is
operated within its specified thermal values. The max value for the SOC is listed in chapter 2.4.
So there may be system implementations where the heat-spreader temperature could be
higher.
Anyway, in this case it has to be validated that there are no thermal specification violations of
any assembled part or integrated circuit over the system temperature range even at worst case
conditions.
Additionally, MSC offers appropriate heat-sink solutions for the different C10M-BT modules
depending on the power dissipation of the implemented CPU. For more information please refer

Operating Temperature Range
There are two operating temperature ranges specified for the MSC C10M-BT / MSC C10M-BTC
COM Express module:
The operating temperature range for commercial modules is defined from 0°C to +60°C.
The operating temperature range for industrial modules is defined from -40°C to +85°C.
At temperatures above +60°C the memory refresh rate must be doubled with BIOS option
Enabled
